Thank you for using the HP forum.

Error : Design jet T3500 Failed new printhead

 

Problem Description: Printhead rejection issue

 

The possible cause could be: Faulty printhead

 

Corrective Action:

 

1. Make sure cartridge levels are above 40% while replacing printhead.


2. Remove all the cartridges from the plotter and printhead.


3. Turn on the plotter without cartridges and printhead, if it gives message as: missing printhead
first install all the cartridges one by one and then continue with printhead replacement.


4. When it gives message : missing printhead, make sure cartridges are inserted first and then printhead for the replacement to be completed successfully


5. After doing all the above steps, if still error persists, try upgrading firmware in the plotter.


6. After Firmware upgradation, follow same steps 1,2, 3 and 4 it should complete the process.


7. If still issue persists, might be printhead has gone faulty, get the printhead replaced from vendor\dealer\HP ARC.

I had similar problem, but corrected it by cleaning the contacts on the printhead AND the carriage with alcohol.  I used a cotton swab soaked in alcohol.  Also, a little "wiggling" (slight side-to-side) action when seating the printhead helped to insure a good contact.  Good luck!
